A gas turbine engine comprises a combustor, a nozzle guide vane assembly. The combustor includes a burner (11), a swirler assembly (12), and a combustion chamber (13, 14). The nozzle guide vane assembly comprises a plurality of nozzle guide vanes (20). Further, the gas turbine engine comprises a charging means (22) connected to the nozzle guide vanes (20) and adapted to selectively electrostically charge the nozzle guide vanes (20) at a pre-determined polarity. In a method of operating a gas turbine engine, fuel and air are introduced in the combustion chamber (13, 14) by the swirler assembly (12), and the nozzle guide vanes (20) are charged electrostatically at a pre-determined polarity.
